Bhai Roop Chand ji Was also Khokhar who was devout sikh of Guru Hargobind Ji. There is village on his name Bhai Roopa in Bhatinda district of Punjab, India. Haral, Ajra, Bhalu and Bhala are the sub gotras of the Khokhar Jats.

Khokhars origin is from Central Asia. They were perhaps Central Asian Huns who repeatedly attacked North India.

They were same for north India's empires as barbarians or Huns were for Roman Empire.

They have very ancient and important history that needs to be researched. Khokhar Jats are said to have constructed fort at Kanwat village in Sikar district of Rajasthan. It was their capital.

H.A. Rose[16] writes that The Awans in Kapurthala are said to have the Jand got.

In Pakistan Khokhars are followers of Islam. A former high commissioner of Pakistan in India was Riaz Khokhar.

It has been mentioned in Indian History that Mahmud Ghazni had given a vow to the Khalifa to invade India every year, demolish the idols they worshipped and spread Islam. Every time he came like a hurricane looted, and returned but only to create a large Army with that wealth, and invade again. Two of his invasions were purely against Jats and these proved the costliest.

In 1001 AD Mahmud of Ghazni defeated Jay Pal and occupied the state of Bhatis, Bhatinda. He captured Multan and levied tax on acts of worship. Anand Pal, son of Jay Pal, took with him the rulers of Kannauj and Jujhauti and attacked Mahmud. In this war Gakkhar Jats were also with Anand Pal. Mahmud had come this time with a huge army and camped for 40 days. At last the army of Gakkhars attacked Mahmud at place called Chhachh near Atak. The Turk army could not sustain war before Gakkhars. Mahmud was about to withdraw from the war, But unfortunately at the same time the elephant of Anand Pal got angry, which sent the signals as a defeat and the army got demoralized. This led to the victory of Mahmud. (Dr Natthan Singh, 123-124)

The Rajput kings of those days did not offer any appreciable resistance against his invasions. Once it was rumored that an attack on Somnath temple was imminent and it would be looted and devastated. All the Rajput Kings assembled there to save Somnath temple from this anticipated disaster, but had no mutual confidence among themselves. They had no heart to fight, but presented themselves only as a matter of prestige. The Head priest of this temple, however, assured them that there was no need to fight as the idol of Somnath would curse the devils to blindness, and they would perish moaning and screaming.

The rumor came true. The Muslim force laid siege of the temple and the battle ensued. At that time a dance of beautiful girls (devdasis) was going on in temple to appease the idol and all Rajput chiefs who had come to defend the temple were busy in enjoying the function. When the Muslim invaders attacked, the Rajputs took to their heels. The priests, however, fought bravely and were killed in large numbers at the altar. Sultan Mahmood demolished the idol of Somnath and started towards Ghazni with a Caravan of Camels laden with gold, silver and precious jewels.

It is mentioned in Todd's Rajasthan that while the Army of Mahmood Ghazni with the booty was passing through the Jat territory of Multan, they were ambushed by Jats in 1025 AD, and all the wealth was recovered.

Sultan Mahmood Ghazni collected the remnants of his force, and managed to slip away with it. This was the first occasion when he met defeat in India.

The King Jai Chand was at daggers drawn with Prithvi Raj. He continued a clash between Mohammed Gauri and Prithvi Raj, and promised to support Mohammed Gauri with men and material. Mohammed Gauri jumped at the proposal. Unlike Mahmood Ghazni his aim was not more plunder. He wanted to capture the throne of Delhi and to establish his empire there. Muhammad Ghori (1173-1205) invaded in 1191 and faced Prithvi Raj Chauhan at Tarain near Delhi. Jats fought along with Rajputs. Prithvi Raj's commander-in-chief was Chand Ram, Dahima Jat. Ghori was defeated and wounded and his troops were looted by Jats while retreating.

It has been mentioned in the chronicles of Jat 'Sarv Khap', which are still reserved with Chaudhry Qabul Singh Shoron Distt Muzaffarnagar, Uttar Pradesh, that the Jat Sarv Khap, reinforced Prithvi Raj with 22,000 brave Jats, who contributed a great deal for Prithvi Raj to win the day.

To avenge his humiliation and defeat he attacked again and won at Tarain (1192). Ghori made Kutb Uddin Aibak his regent at Delhi.

The Jats under Jatwan beseized the Muslim commander of Hansi (Haryana), Nasrat Uddin, raised the sieze and an obstinate and fierce battle defeated the Muslims under Kutb Uddin Aibak (1193). KhokharJats killed Ghori (March 15, 1205) at Dhamyak near Lahore after a fierce battle and avenged the defeat of Tarain.
